CARBON NANOTUBE COMPOSITE HAVING IMPROVED PRESSURE-RESISTANCE SENSITIVITY, METHOD FOR MANUFACTURING THE CARBON NANOTUBE COMPOSITE, AND PRESSURE SENSOR INCLUDING CARBON NANOTUBE COMPOSITE

摘要

The present invention relates to a carbon nanotube composite having improved pressure-resistance sensing sensitivity, a method of manufacturing the carbon nanotube composite, and a pressure sensor including the carbon nanotube composite. A polymer matrix of polydimethylsiloxane, carbon nanotubes, and silver nanoparticles are mixed at a mass ratio of 1 : 0.0018 to 0.0022 : 0.032 to 0.048, and the carbon nanotube and the metallic nanoparticles are uniformly distributed over the polymer matrix. The silver nanoparticles are not attached to a surface of the carbon nanotube, but the carbon nanotube and the silver nanoparticles are uniformly distributed over the polymer matrix. Accordingly, the linearity of the carbon nanotube can be improved, the carbon nanotube composite has improved sensing sensitivity, and the carbon nanotube composite can be manufactured very simply.
